The new Sorensen Series XEL-P DC linear
power supplies are ideally suited to bench
work as well ATE tasks. The Sorensen Series
XEL-P DC linear power supplies are
characterised by extremely low ripple (0.4
mV rms) and user-friendly, lockable analogue
controls. Control ports include RS232, USB
and Ethernet LAN and an optional GPIB
interface. The Ethernet interface is LXI (Lan
eXtension for Instrumentation) compliant. In
addition analogue control (0-10 VDC) for
current and voltage setting is provided as
standard.
The Sorensen Series XEL-P DC linear power
supplies are 3U modules that can be
assembled in 12U cabinets. Models are
available as single output and dual output
(6U) in ratings of 0 to 15 Volt (0-5 Amp), 0
to 30 Volts (0-3 Amps), 0 to 60 Volts (0-1.5
Amps)-single output, and in dual output
versions of 0 to 30 Volts (0-6 Amps when
paralleled).
The new Sorensen Series XEL-P DC linear
power supplies have unique features
including the so-called ‘V-Span’ function
which permits an engineer to set arbitrary
(within 0 to max rated voltage) upper and
lower limits of voltage, covering the entire
range of the analogue knob rotation control;
the above-mentioned lockable voltage and
current settings; and for dual output
models, three operational modes
(independent, true parallel, and tracking
modes). In the independent mode, the two
voltage outputs are electrically isolated
from one another and independently
adjustable. In the isolated tracking mode,
the outputs are still electrically isolated
but have identical values. In the
ratio-tracking mode, one output voltage can
be set as a percentage ratio of the other,
while remaining electrically isolated.
The Sorensen Series XEL-P DC linear power
supplies are readily integrated into ATE
systems, having output terminals also
brought out to the rear panel. The RS232
output is suitable for control systems where
response speed is not of importance. The USB
port is particularly useful Smaller PC
oriented systems. A USB driver is provided
that supports Windows 2000 (note: an IVI
driver is included for operation application
software such as LabView and LabWindows), XP
and Vista. The LAN interface uses standard
10/100 base T Ethernet hardware, and is
suitable for local area networks or direct
connection to a single PC.
